VETERINARY SURGICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 348,044, dated August24, 1886.

Application filed June 28, 1886. Serial No. 206,491. (No model.)

To all whom it may concern:

Be it known that we, CLARK ODELL, WARREN ODELL, and LESTER L. ODELL,citizens of the United States, residing at New Market, in the county ofTaylor and State of Iowa, have invented certain Improvements in theMethod of and Apparatus for Oastrating Animals, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 represents an elevation of our device, s'howing the movable armthrown out-.

ward. Fig. 2 is a similar view showing the position of the parts duringthe process of castration. Fig. 3 represents a longitudinal sectionalview of Fig. 2.

Our invention relates to devices employed in veterinary surgery forcastrating horsesor other animals; and it consists in a method ofsevering the testicle-cord by a roller process without the shedding ofblood, and, secondly, in the peculiar construction and combination ofelements forming the apparatus, all of which we will he;einafter fullydescribe and claim.

To enable others skilled in the art to which our invention appertains tomake and use the same, we will now describe its construction andindicate the manner in which we have carried it out.

In the said drawings, a stationary arm, A, and a movable arm, B, form aclamp, between which the testicle-cord is securelyheld during theprocess of castration. The stationary arm A has a flanged and bifurcatedend, A, thus forming an elongated slot, a, within which is pivotallysecured at]; the movable arm B of the clamp. This arm B is also providedwith aflange, 0, having a curved face, d, thereby forming a guide, uponwhich travels a roller, the purpose and operation of which will behereinafter fully described.

Suitable lugs, 0, project from the sides of the stationary arm and havefulcrumed between their outer ends a bent lever, D, the short arm ofwhich is bifurcated to receive a roller, E, pivotally secured withinsaid .arm. The roller E moves within the slot a, formed in thestationary arm A, and travels in con tact with the curved face d of themovable arm, so as to sever the cord held by said arm.

During the process of castration the operator grasps the instrument withone hand, the two arms of'the clamp gently confining the testicle-cordbetween them. The operator now grasps the lever D with his other hand,and, moving the same, causes the roller E to travel back and forth oversaid cord until the same is pressed off, which operation is readilyaccomplished and without the loss of blood, as the numerous experimentsrecently made by us attest.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The stationary arm A and the movable arm B, forming a clamp, incombination with the lever D, mounted on the stationary arm, and theroller E, loosely mounted in said lever, substantially as hereindescribed.

2. The stationary arm A, having a slotted portion, a, and the movablearm 13, having a flange, 0, provided with a curved face, in combinationwith the lever D, fulcrumed upon the stationary arm, and a rollermounted in said lever and engaging the curved face of-the movable arm tosever the testicle-cord confined thereby, substantially as hereindescribed.
